Application filed June 4, 1914. Serial No. 843,037.

To all 207mm t may concern Be it known that I, FRANK CORNELIUS Kninrn'rnron, a citizen of the United States, residing at Amory, in the county of Monroe and State of Mississippi, have invented a new and useful Plow-Stock, of which the following is a specification.

The invention relates to improvements in plow stocks.

The object of the present invention is to improve the construction of plow stocks and to provide a simple, eliicient and comparatively inexpensive plow stock of light, strong, and durable construction, capable of ready adjustment to enable the plow stock to work diiierent kinds of shares, shovels, etc.

A further object of the invention is to provide a plow stock having means for adjustably mounting a colter and for enabling the same tov be readily removed, replaced, and securely fastened in position for use.

With these and other objects in view the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size,

and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacriicing any of the advantages of the invention.

ln the drawing, Figure l is a central vertical longitudinal sectional view of a plow stock constructed in accordance with this invention. Fig. 2 is a rear elevation of the same. Fig. 8 is a transverse sectional view on the line 3 3 of Fig. 1. Fig. il is a transverse sectional view on the line 4--4 of Fig. l. Fig. 5 is a detail sectional view on the line 5-5 of Fig. 1.

Like numerals of reference designate cor-` responding parts in all the ligures of the rawing.

j In the accompanying drawing, in which is illustrated the preferred embodiment of the invention, 1 designates a channeled plow beam designed to be constructed of steel or other suitable material and preferably tapered forwardly Aand rearwardly from an intermediate point, as clearly shown in Fig. l of the drawing. The plow beam l is composed of spaced side flanges 2 and a top connecting portion 3, the rear terminals 4 of the side flanges being extended rea-rwardly beyond the top connecting portion to provide lugs or ears which form a bifurcated rear end in which a standard 5 is adjustably pivoted by a transverse bolt 6. The standard, which is also channeled, is composed of spaced side flanges 7 and a connecting portion 8, and is provided in its side flanges with perforations 9a arranged at intervals at the intermediate portion of the standard and adapted to receive the bolt 6 to permit the rear end of the plow to be cone nected with the standard at different points along the latter. The standard and the plow beam are also capable of relative pivotal adjustment to arrange the standard to different inclinations, and the parts are rigidly secured in their adjustment by an inclined brace 9, secured at its upper end between the side ianges 2 of the beam by a transverse bolt l0, and having its lower portion extending through a slot 11 in the standard and secured to the latter by a transverse bolt 12. The inclined brace 9 extends upwardly and forwardly from the lower portion of the standard, and its upper end is maintained in a central position between the side flanges 2 of the plow beam by a spacing sleeve 13, arranged on the transverse bolt 10 and provided with a central slot 14 into which the upper end of the brace 9 extends. The slot 11 is formed in the connecting portion 8 of the standard and the lower portion of the inclined brace 9 is provided with a plurality of perforations l5, arranged at intervals and adapted to receive the bolt 12 to permit a relative adjustment of the brace and the standard. The relative adjustment of the standard and the plow beam enables the plow stock to be arranged for working dii1- ferent kinds of plow shares, shovels, and other cultivating blades.

The plow stock is equipped with inclined plow handles 16 located at opposite sides of the standard and arranged at an angle to each other and to the said standard, as clearly illustrated in Figs. 2 and 3 of the drawing. The plow handles, which are connected by upper and lower rungs 17 and 18, are secured at their lower ends to the outer faces of the side flanges 7 of the standard by a transverse bolt 19, and the said plow handles are connected with the upper end of the standard by means of angularly bent arms 20, formed integral with the side flanges 8 and composed of lower or inner laterally extending portions and upwardly i projecting outer portions.

The upwardly projecting outer portions of the arms 20 diverge upwardly and lit against the inner faces of the plow handles, being secured to the same by the lower rung 18, which preferably consists of a rod having a head at one end and threaded at the other end to receive a nut 21. By this construction the plow handles are rigidly secured to the standard. The standard is provided at its lower end with la longitudinally curved plate 22, arranged between and extending across the space between the side flanges 7 and having terminal portions 23 and 24E extending upwardly or inwardly and fitted against the inner face of the connecting portion 8 of the standard.v The upper terminal portion 24 is riveted to the connecting portion 8 and the said plate or piece 22 is provided between its ends with a bolt opening 25 registering with a bolt opening 26 of the connecting portion 8 of the standard and adapted to receive a fastening device for securing a plow share or shovel to the standard. The rearwardly curved or bowed plate 22 is resilient and operates, in a measure, to cushion the share or shovel.

rIhe plow beam is provided at a point intermediate of its ends, preferably at the apex formed by its tapered portion, with a slot 27, adapted to receive a colter 28, which also extends through a slot 29 of a bracket or plate 30, arranged between the side lianges of the plow and composed of a bottom hori- Zontal portion and upwardly diverging front and rear portions having their terminals riveted or otherwise secured to the inner or lower face of the connecting portion 3 of the plow beam. The colter, which has a tapered lower portion, is provided at the front thereof with a cutting edge 31, and the upper portion of the colter is provided at the front edge with notches 32 forming teeth for engaging the front wall of the slot 27. The slot 27 is formed in the top connecting portion 3 of the plow beam, and the upper notched or toothed portion of the colter is maintained in engagement with the said front wall of the slot 27 by a wedge 33, located in rear of the colter and interposed between the same and the rear walls of they slots 27 and 30. The wedge, which preferably has its upper terminal 34 bent laterally to enable it to'be readily grasped, forms a convenient means for adj ustably securing the colter to the beam, and it' will enable the colter to be readily removed and replaced and it securely fastens the colter to the beam.

rlhe beam is provided at its front portion with a plate or member 35 located within the plow beam and extending entirely across the space between the side flanges thereof, and provided at its front end with a vertical fiange 36 arranged in flush relation with and closing the front end of the plow beam. The

rear portion 37 of the plate or member 35 is inclined and has a terminal attaching portion 33 fitted against the lower face of the connecting portion 3 of the plow beam and riveted or otherwise secured to the same. The front flange 36 is provided with an opening 39 and the body portion of the plate or member 35 has an opening a0 arranged in vertical alinement with an opening 41 in the connecting portion of the beam. The openings 39, 40 and l1 enable a suitable draft attachment to be fastened to the front of the plow beam.

TWhat is claimed is 1. A plow stock including a beam, a channeled standard arranged at and extending above and below the rear end of the beam and provided below the same with a slot, said standard being also provided in its side flanges with perforations arranged at intervals, a pivot piercing the rear end of the beam and adapted to be arranged in the perforations of theJ side flanges of the standard for adjustably connecting the same to the beam, an inclined brace pivotally connected at its upper end to the beam and extending downwardly and rearwardly through the slot 'of the standard, a fastening device piercing the lower portion of the brace and the side franges of the standard and adjustable on one of said parts, and handles secured to and carried by the standard in its adjustment.
